Review request for Ambari, Jonathan Hurley and Nate Cole.


Bugs: AMBARI-15161
    https://issues.apache.org/jira/browse/AMBARI-15161


Repository: ambari


Description
-------

If the database shows a {{VERSION_MISMATCH}} for a host component, correcting this component
doesn't set the data back:

{code:title=hostcomponentstate}
1	2	ZOOKEEPER_CLIENT	2.4.0.0-86	3	INSTALLED	1	ZOOKEEPER	NONE	UNKNOWN
2	2	ZOOKEEPER_SERVER	2.4.0.0-86	4	STARTED	1	ZOOKEEPER	NONE	UNSECURED
3	2	ZOOKEEPER_SERVER	2.4.0.0-86	4	STARTED	2	ZOOKEEPER	NONE	UNSECURED
4	2	ZOOKEEPER_CLIENT	2.4.0.0-86	3	INSTALLED	2	ZOOKEEPER	NONE	UNKNOWN
5	2	ZOOKEEPER_SERVER	2.4.0.0-86	4	STARTED	3	ZOOKEEPER	VERSION_MISMATCH	UNSECURED
{code}

Notice that there is a {{ZOOKEEPER_SERVER}} which has had it's version corrected back to {{2.4.0.0-86}}
but still shows as {{VERSION_MISMATCH}}

STR:
1) Stop ZK on a host
2) {{hdp-select}} to another version
3) Start ZK
4) After {{VERSION_MISMATCH}}, stop it again, flip it back, and start it

First test run failed once with

  UpgradeActionTest.testFinalizeDowngradeAcrossStacks:784 null
  UpgradeActionTest.testFinalizeWithHostsAlreadyCurrent:619->makeUpgradeCluster:329 expected:<1>
but was:<2>
  ClusterTest.testTransitionHostVersionAdvanced:1818 null
  
but successive test runs both from IDE and from console did not reproduce that. Maybe my mistake
during first run


Thanks,

Dmitro Lisnichenko
